Description

ATSv2 model lacks retrieval of list-of-all-apps, list-of-all-app-attempts and list-of-all-containers-per-attempt via REST API's. And also it is required to know about all the entities in an applications.

It is pretty much highly required these URLs for Web UI.
New REST URL would be

1. GET /ws/v2/timeline/apps
2. GET /ws/v2/timeline/apps/{app-id}/appattempts.
3. GET /ws/v2/timeline/apps/{app-id}/appattempts/{attempt-id}/containers
4. GET /ws/v2/timeline/apps/{app id}/entities should display list of entities that can be queried.
